IMPROVEMENTV IN CARPENTERS BEVELS.

Specification forming part of Letters Patent No. 141,081, dated July 22, 1873; application led May 2, 1873.

To all whom 15mm/concern:

Be it known that I, SAMUEL D. SARGENT, of the city and county of Hartford and State of Connecticut, have invented a new and useful Improvement in Carpenters Bevel; and to enable a person skilled in the art to make and use the same I will proceed to describe it, referring to the drawings, in which the same letters indicate like parts.

The nature of this invention consists in the mode of tightening the blade in the stock by means of two pieces of metal, viz., a bolt and a cone-shaped end thumb-screw, arranged laterally within the stock, and operated from the end of the stock.

In the accompanying drawings is shown a sectional view of this invention.

a is the metal stock made in two parts. Each part is made in shell form. The circular end is made solid or iush a short distance from the end to providebearing-surface for the blade b, through which a central orifice is formed to receive a bolt, c, iiush with each side of the stock. This bolt c is provided with an orifice, d, just inside from its headless end,

or between the side of the blade and its end7 and is made incline shape on the side nearest to its end. c is a cone-shaped end thumb-screw tted into one part of the stock, extending from the back end through the chamber, having a screw, h, near its cone-shaped end h', which enters a screw threaded orifice, h, formed directly at right-angle with the bolt orice d., and by turning the thumb-screw in one direction the two parts of the stock will be rmly compressed against the blade, which will be held more firmly in its desired position than by any device heretofore known.

Thus I am enabled to produce a more perfect bevel, and one cheaper of manufacture.

What I claim, and desire to secure by Letters Patent, is-

The cone-shaped thum b-screw e arranged laterallyin the stock, in combination with the bolt c, substantially as and for the purpose set forth.

SAMUEL D. SARGENT.
